Hi Matrimony,
Welcome to the forums, and congratulations on the new job! It sounds like good work, even if it is a bit more thrilling at times than you bargained for. While I don't have direct personal experience with acrophobia as such, I have definitely felt that vertiginous, woozy feeling when looking down. It's a completely normal, natural biological reaction, and we're some of the first humans in history to have jobs that require us to go up that high routinely!
In an ideal world with unlimited time, you might work your way up gradually to higher and higher heights as you become physically comfortable with each one. However, in this workplace context, it may be a case of "fake it till you make it." Presumably you are strapped in and all the proper precautions to ensure your physical safety have been put in place, so it's then a matter of convincing the rest of your body that you are in fact safe.
This will probably take some time, and as you say it's a new job, so be patient with yourself. You might also practice some very basic in-through-the-nose, out-through-the-mouth breathing while you're safely on the ground. That way, when you're up checking the silo, you will have had practice just focusing on your breath and bringing your attention back to the task at hand.
Unfortunately there isn't a miracle cure, and I suspect you will become used to it over time, even if that's not the most satisfying answer. It sounds like your supervisor is a fellow traveler and might help you brainstorm a way to split the work with someone else who doesn't mind heights as much?
Just some thoughts!
